DNA barcoding has revolutionised science. Ask anyone working in evolution or taxonomy these days what the biggest changes are the they’ve seen in their discipline, chances are it’ll be to do with gene sequencing and DNA processing. So when the International Barcode of Life (iBOL) Conference came to Trondheim last week, I jumped at the opportunity to learn more about the behind the scenes work that goes into cataloguing the DNA barcodes of life on earth.

I sat down with Donald Hobern, Executive Secretary of iBOL and former Executive Secretary of the Global Biodiversity Information Facility (GBIF) and Director of the Atlas of Living Australia (ALA). Donald joined iBOL just as they launched BIOSCAN, a $180 million dollar program which aims to accelerate the cataloguing of the world’s biodiversity in DNA form. We spoke about BIOSCAN, the technology behind bringing occurrence and genetic data together, and how the work iBOL and GBIF do ties into the bigger picture of global conservation and sustainability.

Humans have always tried to categorise the world around us. From our early interpretation of the four elements to Linnaeus’ revolutionary system in the 1700s, we’ve always sought to understand better the life that we share the planet with. On my visit to the University of Guelph this year, I was able to sit down with a scientist who is attempting to classify all multi-cellular life.

Professor Paul Hebert is Scientific Director of the International Barcode of Life project, a consortium whose goal it is to document all life on our planet. I spoke with the man nicknamed the “father of DNA barcoding” about the magic that has revolutionised biodiversity science in the last 50 years, and how it’s being used today.

If you’ve read some of our previous posts on invasive species, you’ll have learned that they can be a real danger to local ecosystems and economies, and even have impacts on our health. But as Vanessa Bieker writes, there is a silver lining, and that comes in the form of what invasive species are teaching us about evolution.
